IMPROVEMENT IN DAMPERS.

Specification forming part of Letters Patent NO. 43,794, dated August 9, 1864.

.T 0 all whom it may concern.'

Be it known that I, HYLAND RAYMOND, of Racine, in the county of Racine and State of Wisconsin, have invented a new and Im proved Heat-Radiator for Stoves, Furnaces, ctc.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part o f this specification, in which` Figure l is a vertical central section of my invention, taken in the line :c w, Fig. 2, Fig. 2, a horizontal section of the same, taken in the line 1/ y, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to a new and improved heat radiator designed to be applied to the pipes of stoves, furnaces, and the like to prevent the heat from passing into the ue or being carried off by the pipe and cause it to be radiated into the room.

The invention consists in the employment or use of a drum provided at bot-h ends with a collar to receive the ends of the pipe which communicate with it, thedrum having a circular plate placed transversely in it, the plate being smaller in diameter than the drum, and the latter also having an annular plate arranged within it, which performs the office ot' a vulve, while the plate first mentioned serves as a seat for the valve, all being so arranged as to admit of the draft being controlled and regulated with the greatest facility, and to insure the radiation of heat from the drum as desired.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a drum, which may be of any suitable dimensions and provided with ends B of conical form, which have collars a at their centers to receive the ends of the pipe which communicates with the drum.

Within the drum A there is placed a horizontal circular plate, O, which is somewhat less in diameter than the drum, as shown in Fig. 1. This plate C is supported by and attached to bars b, the lower ends of which rest upon or are attached to the lower end, B, of the drum, the plate C being rather above the center of the drum.

Within the drum A there is fitted a cylinc of the plate E being directly over the center y of the plate G. The plate E has a rod, d, at-

tached to it, and this rod passes through two oblique or diagonal slots, c c', in the drum A at opposite sides of it and in reverse positions, one of said slots, e', having notches fmade in its lower edge to receive the rod d and hold the cylinder D, and consequently the plate E, at any desired height. When the cylinder D is fully down, the plate E rests upon the plate C, and all communication between the lower and upper part of the drum will be cut off, as the plate E performs the ofce of a valve, and the annular plate C is the seat thereof. When the cylinder D is elevated, as shown in red in Fig. l, the products of combustion pass upward around the edge of the plate C and through the central opening, c, of plate E, as indicated by theI arrows in Fig. l; and it will be seen that the strength of the draft may be regulated by raising the plate E to a greater or less height, said plate E being retained at the desired point by the rod d, fitting in the proper notch, j', of the slot c. This arrangement of the stationary plate G and rising and falling plate E, as shown and described, causes the products of combustion in passing upward through the drum A to impinge against the side of the latter below the plate E, and the heat will consequently be radiated from the drum, and the products of combustion will pass from the drum above the plate Ein a comparatively cool state into the pipe above it. This heat radiator may be constructed at a very moderate cost, and will effect a great saving in the consumption of fuel. The cylinder D and plate E are raised in the drum A by simply moving the rod d to the right or upward in the slots c c', and said parts are lowered by moving the rod d downward in the slots.

I would remarkA that although the drum A is represented in a vertical positionI such position is not strictly necessary for the perfect operation of the device. It may, if required in any case, be placed in a horizontal position. I would further remark that the annular plate E may be stationary, and the plate C arranged to move, but the device would be substantially the same in either ease. A

Having thus described my invention, what I Claim as new, and desire to secure by Letters Patent, is

The annular plate E, in combination with the plate C, of less diameter than the drum A, the two plates heilig arranged Within the drum, and one of them being movable, to operate in the manner substantially as herein set forth.
